Duplication introduced by
This method seems to be duplicated in your project.

Duplicated code is one of the most pungent code smells. If you need to duplicate the same code in three or more different places, we strongly encourage you to look into extracting the code into a single class or operation.

You can also find more detailed suggestions in the “Code” section of your repository.

Comprehensibility Bug introduced by
It seems like you call parent on a different method (stream_tell() instead of stream_seek()). Are you sure this is correct? If so, you might want to change this to $this->stream_tell().

This check looks for a call to a parent method whose name is different than the method from which it is called.

Consider the following code:

class Daddy
{
    protected function getFirstName()
    {
        return "Eidur";
    }

    protected function getSurName()
    {
        return "Gudjohnsen";
    }
}

class Son
{
    public function getFirstName()
    {
        return parent::getSurname();
    }
}

The getFirstName() method in the Son calls the wrong method in the parent class.
